Before doing anything begin by upgrading the firmware and put dongle on a long USB extension cable:
“Network formation refused, RF environment is likely too noisy. Temporarily unscrew the antenna or shield the coordinator with metal until a network is formed.”
If “RF environment is likely too noisy” then should also take actions to avoid interference sources, see:

As mentioned there take note to use the dongle in either a USB 2.0 port or via a powered USB 2.0 hub because as Zigbee is especially sensitive even USB 3.0 ports/cables generate interference on 2.4GHz.
Then later after getting it working also read this before starting pairing devices:
